About this Help
This online help was created for Forcepoint Next Generation Firewall (Forcepoint NGFW), version 6.9.0.
Introduction to the Forcepoint Next Generation Firewall solution
Before setting up Forcepoint Next Generation Firewall (Forcepoint NGFW), it is useful to know what the different components do and what engine roles are available.
Deployment
Before you can set up the system and start configuring elements, you must consider how the different SMC components should be positioned and deployed.
Setting up
After deploying the SMC components, you are ready to start using the Management Client and carrying out some of the first configuration tasks.
Monitoring
You can use the SMC to monitor system components and third-party devices. You can also view and filter logs, and create Reports from them.
Controlling NGFW Engines
You can command and set options for engines through the Management Client or on the engine command line. You can also stop traffic manually.
SMC configuration
Security Management Center (SMC) configuration allows you to customize how the SMC components work.
NGFW Engine configuration
You can create and modify Firewalls, IPS engines, Layer 2 Firewalls, Master NGFW Engines and Virtual NGFW Engines. You can configure the NGFW Engine properties, activate optional features, and configure advanced NGFW Engine settings.
Routing
Use the Management Client to configure static or dynamic routing, and use a Multi-Link configuration to manage and distribute inbound and outbound connections.
Traffic inspection policies
Policies are key elements that contain rules for allowing or blocking network traffic and inspecting the content of traffic.
Users and authentication
User accounts are stored in internal databases or external directory servers. You can use Forcepoint NGFW in the Firewall/VPN role or external authentication servers to authenticate users.
Virtual private networks
Forcepoint NGFW supports both policy-based and route-based VPN (virtual private network) tunnels between VPN gateways. For full remote access, Forcepoint NGFW supports both IPsec and SSL VPN tunnels for VPN clients.
Maintenance and upgrades
Maintenance includes procedures that you do not typically need to do frequently.
